Fuse 1500VAC 4A to 9A
« on: April 10, 2024, 01:08:05 pm »
Hi
I got a project working with 1500VAC and 4,5A to 9A.
For this project I'm looking for some fuses capable of 1500VAC but the only thing i can find is 1500VDC photovoltaic.
Fuses designed for distribution transformer protection is not suitable because they are to large and to slow.
I'm looking for something that is 10 to 15mm thick and 85mm to 150mm long. Also fuse holders.
It is going to be panel mounted and personnel will not have access to the fuses when energized.

Please come with reccomandations.

From my experience this will be difficult.
If in EU search for 'GS Semiconductor fuses' ' IEC269 -IV'
If in USA try 'Norberg~IES 4237 South 74th East Avenue Tulsa, Oklahoma 74145'

But I did not see any small fuses above 1000/1200 Vac.
You might put RFQ to one of these, or similar providers.
Provide the the fault level and type of bus protection upstream.

I'd check out SIBA https://siba.de/en/products/fuse-detector/fuse-detector.html?fdf[produktgruppe]=Sem.Cond.Prot.+Fuse-Link
The product selector page lists by part number. You have to work hard to find their product pages in amongst a forest of PR wankery.
Crap Site SIBA!!

Use photovoltaic fuses. If the fuse can break 1500VDC, then breaking 1500VAC won't be a problem. It's much more difficult to break DC, than AC.

What breaking capacity do you require?

...

Yes, the breaking capacity (prospective fault current of the source) is an extremely important parameter.
